win xp pro runing two dual core xeons

[Guest]

Hi
I am thinking of building workstation with 2 dual core xeons.
With HT enabled system will have 8 (logical) cpus.
My question is will WIN XP pro handle 8 cpu system?
If not, any other operating system(NOt expensive) recomendations?

Thanks

Two dual core cpus will only give you four logical processors.

However, I don't believe XP Pro can handle more than two.

Hi tfw

Two dual core cpus will only give you four logical processors

well: 4 phisical and 4 logical processors.

Hi tfw
well: 4 phisical and 4 logical processors.

It's confusing but in reality it's 2 cpu's each with 2 cores, each core with
two logical processors. Microsoft has stated the license is for the number
of cpu's regardless of the number of cores or logical processors.

Hi Kerry.
May be we sould use correct terms.
In dual xeon setup board will contain 2 dual core xeons.
Each socket is one processor for the XP pro.
each processor contains 2 cores, so we have 2 socket*2 cores=4 cores.
If we enable HT, each core will have 2 logical 'cpu', so 4 cores * 2 = 8 'cpu'
so XP pro's task manager wil show 8 'cpu' .

Hi tfw

Windows XP Pro can only support 2, so you would need some thing like
Server 2000/2003 to get the maximum performance out of your hardware
(do note that windows servers only support 32 logical proccessors),
unless you do the clever thing and switch to Linux/BSD (do note that,
in theory, Linux/BSD supports an unlimited number of logical
processors).
